Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to an automobile lamp module and an automobile. Background Art

[0002] In the prior art, the high-beam beam pattern (light spot) of LED dual-lens headlights is generally circular, oblate, or rectangular. This type of light spot presents significant deficiencies in both the driving experience and the visual quality of the road ahead. First, this type of light spot cannot illuminate the road surface at a significant distance when in high beam mode, resulting in insufficient road brightness for the driver. This requires the driver to concentrate intensely and diligently to detect obstacles in the dark ahead. Maintaining this state for extended periods can easily lead to driver fatigue, compromising driving comfort and safety. Second, this type of light spot presents significant drawbacks when illuminating road signs, particularly those high above highways. Specifically, the beam spot is not high enough, and the lack of a gradient taillight extension in the vertical direction makes it difficult to illuminate road signs. When installing the headlights, raising the high beam will illuminate road signs but will be too bright, glaring, and glaring. This installation method also results in insufficient low-beam road brightness, compromising driving safety. Summary of the Invention

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In the prior art, the high-beam beam pattern (light spot) of LED dual-lens headlights is generally circular, oblate, or rectangular. This type of light spot presents significant deficiencies in both the driving experience and the visual quality of the road ahead. First, this type of light spot cannot illuminate the road surface at a significant distance when in high beam mode, resulting in insufficient road brightness ahead for the driver. This forces the driver to concentrate intensely and strain their vision to detect potential obstacles ahead in the dark. This prolonged state can easily lead to driver fatigue, compromising both driving comfort and safety. Second, this type of light spot presents significant drawbacks when illuminating road signs, particularly those high above highways. Specifically, the beam spot is not high enough, and the lack of a gradient taillight extension in the vertical direction makes it difficult to illuminate road signs. When installing the headlights, raising the high beam will illuminate road signs but will be too bright, glaring, and glaring. This installation method also results in insufficient low-beam road brightness, compromising driving safety.

[0028] In view of this, an embodiment of the present application proposes an automobile lamp module to effectively solve the aforementioned problems.

[0029] See also Figure 1 and Figure 2 As shown, an embodiment of one aspect of the present application discloses an automobile headlight module, which can effectively solve the problem of insufficient headlight illumination height; at the same time, it can also effectively solve the problem of insufficient brightness of the nearby road surface caused by raising the high beam when installing the headlight, thereby improving driving comfort and driving safety.

[0030] The following will be combined Figures 1 to 4 The automobile lamp module disclosed in the embodiments of the present application is specifically explained and illustrated.

[0031] like Figures 1 to 4 The automobile lamp module includes a high-beam reflector cup 110 (not shown in the figure) and a light-emitting module. The high-beam reflector cup 110 is symmetrically arranged about a first plane. A reflective surface 111 cooperating with the light-emitting module is formed on the inner side surface of the high-beam reflector cup 110. The reflective surface 111 includes a first reflective curved surface 1111, a second reflective curved surface 1112, and a third reflective curved surface 1113. The first reflective curved surface 1111 is located in the middle and lower part of the inner side surface. The second reflective curved surface 1112 is provided on one side of the first reflective curved surface 1111, and the second reflective curved surface 111 is located in the middle and upper part of the inner side surface. The third reflective curved surface 1113 is provided on both sides of the first reflective curved surface 1111 and the second curved surface. The first reflective curved surface 1111 and the second reflective curved surface 1112 respectively transition smoothly with the third reflective curved surface 1113.

[0032] The first plane is Figure 4 FF plane in.

[0033] In the automotive lamp module of the above embodiment, the reflective surface 111 in the high beam reflector 110 is formed by fitting a first reflective curved surface 1111 , a second reflective curved surface 1112 and a third reflective curved surface 1113 .

[0034] In one embodiment, the high-beam reflector 110 is mounted on the upper side of the light-emitting module, and the light-emitting module is located below the inner side of the high-beam reflector 110. When the light-emitting module is in operation, the first reflective curved surface 1111 can irradiate the collected light to the upper part of the high-beam spot, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high-beam spot, and the third reflective curved surfaces 1113 on both sides can irradiate the light collected from the left and right sides to the upper middle part of the high-beam spot. In this way, a tall, shield-shaped high-beam spot can be obtained, effectively solving the problem of insufficient illumination height of the headlight. At the same time, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high-beam spot, effectively solving the problem of insufficient brightness of the nearby road surface caused by raising the high beam when the headlight is installed, thereby improving driving comfort and safety.

[0035] It is worth understanding that the light emitting module is arranged on the first plane to ensure that the left and right sides of the obtained far light spot are symmetrical, thereby avoiding brightness differences between the left and right sides of the far light spot.

[0036] In some embodiments of this application, see Figure 2 and Figure 3 The curvature of the first reflective surface 1111 is greater than that of the second reflective surface 1112. In other words, the curvature of the first reflective surface 1111 is greater than that of the second reflective surface 1112. After the light emitted by the light-emitting module is reflected by the first and second reflective surfaces 1111 and 1112, a certain degree of stratification occurs. Furthermore, the first reflective surface 1111 is positioned near the bottom of the high-beam reflector cup, while the second reflective surface 1112 is located above the light-emitting module. This allows the light reflected by the first and second reflective surfaces 1111 and 1112 to illuminate the upper and lower portions of the light spot, respectively. This increases the height of the high-beam spot and helps ensure the brightness of the upper and lower portions of the high-beam spot.

[0037] In some embodiments of this application, see Figure 3 The curvature of the profile of the reflective surface 111 on the first plane gradually decreases from the first reflective curved surface 1111 to the second reflective curved surface 1112. In other words, the curvature of the reflective surface 111 gradually decreases from the first reflective curved surface to the second reflective curved surface 1112, allowing light to converge near the light spot, thereby improving the brightness of the distant light spot.

[0038] In some embodiments of the present application, the curvature of the first reflective curved surface 1111 is greater than the curvature of the third reflective curved surface 1113 .

[0039] In some embodiments of the present application, the area of ​​the first reflective curved surface 1111 is one quarter of the area of ​​the entire reflective surface 111. In this way, the brightness of the upper portion of the distant light spot can be guaranteed.

[0040] In some embodiments of this application, see Figures 2 to 4 The area of ​​the third reflective surface 111 is two-quarters of the total reflective surface 111. Specifically, the third reflective surface 1113 comprises two parts, one located on one side of the first reflective surface 1111, and the other located on the other side of the first reflective surface 1111. The two third reflective surfaces 1113 respectively direct the light collected from the left and right sides toward the upper-middle portion of the far light spot. Furthermore, the light reflected by the two third reflective surfaces 1113 is staggered by a certain distance from the light reflected by the first reflective surface 1111, thereby increasing the width of the far light spot.

[0041] In one possible implementation, see Figure 4 The two third reflective curved surfaces 1113 are symmetrically arranged about the first plane.

[0042] In some embodiments of the present application, the reflective surface 111 is an electroplated surface to form mirror reflection, thereby improving the reflection effect and ensuring the brightness of the distant light spot.

[0043] Another embodiment of the present application provides a car, including the car light module as described above.

[0044] In the automobile of this embodiment, the reflective surface 111 inside the high beam reflector cup 110 of the automobile headlight module is fitted by a first reflective curved surface 1111, a second reflective curved surface 1112 and a third reflective curved surface 1113. Among them, the first reflective curved surface 1111 can irradiate the collected light to the upper part of the high beam spot, the second reflective curved surface 1112 can irradiate the collected light to the lower part of the high beam spot, and the third reflective curved surfaces 1113 on both sides can irradiate the light collected on the left and right sides to the middle and upper part of the high beam spot. In this way, a tall high beam shield spot can be obtained, which can effectively solve the problem of insufficient illumination height of the headlight; at the same time, it can also effectively solve the problem of insufficient brightness of the nearby road surface caused by raising the high beam when the headlight is installed, thereby improving driving comfort and driving safety.

[0045] In one embodiment, see Figure 5 and Figure 6 As shown, Figure 5 This is the existing 3-inch round lens - high beam effect diagram, where the illumination at 25 meters is: 313.666lx / (the illumination at 5 meters is 7825lx), the left and right angles are 90 degrees, and the angle below the cutoff line is 19 degrees; Figure 6This is a schematic diagram of the high-beam effect of an automotive light module in one embodiment of the present application. The diagram shows the high-beam effect using a 3-inch circular lens. The illumination at 25 meters is 336.27 lx (8406 lx at 5 meters), with a left-right angle of 90 degrees. By comparison, the high-beam illumination of the automotive light module in this embodiment is higher, resulting in a better high-beam effect.

[0046] In another embodiment, see Figure 7 and Figure 8 , Figure 7 This is the existing 3-inch square lens - high beam effect diagram, where the illumination at 25 meters is: 297.871lx / (5 meters illumination is 7425lx), the left and right angles are 90 degrees, and the angle below the cutoff line is 20 degrees; Figure 8 This is a schematic diagram of the high-beam effect of an automotive light module in one embodiment of the present application. The diagram shows the high-beam effect using a 3-inch square lens. The illumination at 25 meters is 332.407 lx (8300 lx at 5 meters), with a left-right angle of 90 degrees. By comparison, the high-beam illumination of the automotive light module in this embodiment is higher, resulting in a better high-beam effect.
